MV Overhead Line Protections and their Coordination with Autoreclosers
Šoustal, Petr ; Skala, Petr (referee) ; Orságová, Jaroslava (advisor)
The aim of this Master’s Thesis is to describe protections for overhead lines in distribution networks. Here are described requirements for the protection and the basic protections. Protections are divided according to their protective function. For each protection is given its use and its power plans. It is stated in the work setting of protection in the real network. On this network is simulated place with short-circuit and described the action of protection. The work also deals with the coordination of protection with automatic circuit breakers. This chapter shows that, given the selectivity is not possible to deploy two or more reclosers (remotely-operated switches) to the core network management. The next chapter describes two representatives reclosers available on the Czech market OSM 27 and GVR 27. Chapter describes and compares their performance characteristics. Conclusion the work includes a proposal protected the lead in incorporating automatic circuit breakers (remotely operated circuit breakers and reclosers). The proposal is based on two different levels of annual number of interruptions and duration of annual general interruption of electricity supply. For these levels the company EGÚ Brno, a.s. proposed several variants of the use of remote-controlled in terms of reducing the cost of the penalty. Our task was to choose a variant that would be applicable in the real network. Reducing costs is feasible only in the limits Ln = 6 failures / year and Lt = 720 min / year, where the selected option No. 4. The limits Ln = 8 failures / year and Lt = 1,080 min / year, not in the real network may no option in terms of selectivity.

Who is a designer
Dohnalová, Kateřina ; Staňková, Hana Grulichová (referee) ; Kubíková, Zuzana (advisor)
To what extent can anyone call themselves a designer? Where is the line that decides why and who is a designer? The aim of this bachelor thesis is to answer these simple questions. The author simultaneously draws from her own long term experience, working as a main bartender in a pub, where she tries to redesign the the core processes of this pub based on her participatory observation. As an employee she has a bigger potential of resolving the existing problems, which she finds absurd while working, or she can suggest their solution in a way that is more sustainable and co-worker friendly, but at the same time takes into account the boss and the community that shapes around the said place. The long term employer or an invited expert (designer) doesn't actually perform the job. Which means that they can't assess the situation and recommend a meaningful solution.

The aim of the diploma thesis is to present the institute of work inspection with a focus on Civil Engineering. Another focus is to present health and safety coordinator in relation with the institute of work inspection. I would like to draw from practical experience gained at work so I will visit construction sites with a coordinator and an inspector from the institute and consequently I will try to evaluate these inspections. At the end of the thesis I will focus on risk precautions where I will apply one method with which I will solve a practical example.

MISSING AND DISAPPEARING
Langer, Jan ; Havlík, Vladimír (referee) ; Mikyta, Svätopluk (advisor)
This work documents the author's interest in drawing and is based on the mental background of his artistic creation. The work is guided by the interest in the physical conditions of the drawing itself (materiality of the drawing), but also in the study of drawing as a fluid material of artistic creation, entering into the relationship with the image (drawing as a material). At the same time it deals with the process of creation itself and the phenomenon of repetition. The primary goal of the whole work is not the deliberate laying of pre-formulated questions and the subsequent search for their answers, the presentation of some finished truths, or the mere illustration of a certain issue, but rather the process of finding questions that emerge during the process of creation itself.
